What are the 5 main objectives of epidemiology?
In the mid-1980s, five major tasks of epidemiology in public health practice were identified: public health surveillance, field investigation, analytic studies, evaluation, and linkages..
Are epidemiologists doctors?
Are epidemiologists considered medical doctors? No. While epidemiologists study and investigate the causes and sources of diseases in much the same way as medical doctors, they’re not considered actual physicians. Perhaps the biggest reason why is treatment.
What is epidemiological concept?
Epidemiology is the study of the distribution and determinants of health-related states, conditions, or events in specified populations and the application of the results of this study to the control of health problems.
What is it called when you study diseases?
Epidemiologists are scientists who study diseases within populations of people. In essence, these public health professionals analyze what causes disease outbreaks in order to treat existing diseases and prevent future outbreaks.
How does an epidemiologist describe the burden of disease?
Disease burden is the impact of a health problem as measured by financial cost, mortality, morbidity, or other indicators. It is often quantified in terms of quality-adjusted life years (QALYs) or disability-adjusted life years (DALYs).
What are the 3 main elements of descriptive epidemiology?
Descriptive epidemiology covers time, place, and person.
What are the key concepts of epidemiology?
Epidemiology is based on two fundamental assumptions. First, the occurrence of disease is not random (i.e., various factors influence the likelihood of developing disease). Second, the study of populations enables the identification of the causes and preventive factors associated with disease.
What is the main purpose of epidemiology?
Epidemiology is the study of how often diseases occur in different groups of people and why. Epidemiological information is used to plan and evaluate strategies to prevent illness and as a guide to the management of patients in whom disease has already developed.
How does epidemiology help in controlling diseases?
Epidemiology identifies the distribution of diseases, factors underlying their source and cause, and methods for their control; this requires an understanding of how political, social and scientific factors intersect to exacerbate disease risk, which makes epidemiology a unique science.
What are the basic principles of epidemiology?
Principles of EpidemiologyDistribution – Epidemiology is concerned with the frequency and pattern of health events in a population. … Determinants – Epidemiology is also used to search for causes and other factors that influence the occurrence of health-related events.More items…•Nov 3, 2006
What is an example of epidemiology?
Epidemiological studies measure the risk of illness or death in an exposed population compared to that risk in an identical, unexposed population (for example, a population the same age, sex, race and social status as the exposed population).
What are the types of descriptive epidemiological studies?
Three of the types of descriptive epidemiologic studies are in- dividual case reports, case series, and cross-sectional studies (e.g., a survey of a population). Case reports and case series are among the most basic types of descriptive studies.
Which is the most powerful epidemiological study?
Randomized, controlled clinical trials are the most powerful designs possible in medical research, but they are often expensive and time-consuming. Well-designed observational studies can provide useful insights on disease causation, even though they do not constitute proof of causes.
What does descriptive epidemiology include?
Descriptive epidemiology uses observational studies of the distribution of disease in terms of person, place, and time. The study describes the distribution of a set of variables, without regard to causal or other hypotheses. Personal factors include age, gender, SES, educational level, ethnicity, and occupation.
What are the two main goals of epidemiology?
The objectives of epidemiology include the following: to identify the etiology or cause of disease. to determine the extent of disease. to study the progression of disease.
What are the two goals of epidemiology?
The principal aim of epidemiology is to identify factors related to the occurrence of disease. Identification of these factors both causal ( causation) and risk factors, enable developing a rational basis for prevention ( epidemiology, prevention).
What is the strongest study design?
A well-designed randomized controlled trial, where feasible, is generally the strongest study design for evaluating an intervention’s effectiveness.
What skills do you need to be an epidemiologist?
Epidemiologists should also possess the following specific qualities:Communication skills. Epidemiologists must use their speaking and writing skills to inform the public and community leaders of public health risks. … Critical-thinking skills. … Detail oriented. … Math and statistical skills. … Teaching skills.
What is the best definition for epidemiology?
By definition, epidemiology is the study (scientific, systematic, and data-driven) of the distribution (frequency, pattern) and determinants (causes, risk factors) of health-related states and events (not just diseases) in specified populations (neighborhood, school, city, state, country, global).
What type of study is a descriptive study?
Descriptive studies are observational studies which describe the patterns of disease occurrence in relation to variables such as person, place and time. They are often the first step or initial enquiry into a new topic, event, disease or condition.
What are the 3 major types of epidemiologic studies?
Three major types of epidemiologic studies are cohort, case-control, and cross-sectional studies (study designs are discussed in more detail in IOM, 2000). A cohort, or longitudinal, study follows a defined group over time.
